Dr. Cheyenne Smith of the USGS Eastern Ecological Science Center coaches USGS Idaho Water Science Center hydrologic technician Niko Parrish in dissecting a mountain whitefish from northern Idaho's Kootenai River. The samples for histopathology analyses were collected as part of monitoring and assessment of water quality in the transboundary Kootenai River basin.

Biologists from the Maryland Department of Natural Resources use electrofishing to monitor populations of invasive blue catfish (Ictalurus furcatus) in the Potomac River.

In 2024, the long-term fall migration bird banding station at Patuxent Research Refuge had it's first Prairie Warbler since 2019!  

Scientists at the banding station collect population data, including age and sex. Due to color contrast, Indigo Bunting wings are a great example of the feather wear and replacement that scientists look at to age a bird. This male Indigo Bunting has 3 different feather ages, which tells us it was born last year.

Hooded Warbler are a treat at the EESC Bird Banding Lab Fall Migration Station, as the station bands an average of two each fall. Based on data collected, the individual pictured hatched this year and is a male.

This house wren was banded during the fall migration banding activities at EESC's Bird Banding Laboratory in Laurel, MD.

USGS scientist observing an osprey nest. Use of a mirror pole allows the researcher to observe the nest from a boat without disturbing the nest. The image was taken during a USGS study of osprey (Pandion haliaetus) and their prey (menhaden (Brevoortia tyrannus), and other species of fish) in the middle and lower Chesapeake Bay and its tributaries.
